The present invention is a tailpipe exhaust nozzle device 10 that can beused with a vehicle with a side exhaust pipe that attaches magneticallyand via male/female connection to a tailpipe adapter (TA) placed on theside exhaust pipe (not shown). The tailpipe adapter (TA) is made ofgalvanized steel. The other end of the exhaust pipe nozzle device 10 isattached to an exhaust hose via a 90 degree stainless steel transitionelbow (TE) of a vehicle exhaust removal system, which is then attachedto a spiral duct system that is tied into a central fan to expel thedangerous exhaust fumes from the vehicle to the external environment(not shown) of the protected building. The exhaust hose travels with thevehicle along either a track or suction rail and automatically releasesfrom the vehicle tailpipe at the garage door while expelling thedangerous exhaust fumes at all times that the tailpipe nozzle device isconnected to the vehicle.

FIGS. 1A and 1B illustrate a tailpipe exhaust nozzle device 10 used incombination with a vehicle exhaust removal system to expel vehicleexhaust fumes from a building from a vehicle with a side exhaust pipe(not shown). The tailpipe adaptor (TA) and the transition elbow (TE) areadditional components of the tailpipe exhaust pipe nozzle device 10.

The tailpipe exhaust nozzle device 10 is comprised of a body ringportion 20 that may be in the shape of a cylinder with a bottom 60 thatmay be in the shape of a cylinder and an inner aperture 30 and a maleadaptor 40 that may be in the shape of a cylinder with a side 50 thatmay be in the shape of a cylinder and a top shelf surface 70 that may bein the shape of a cylinder that is integral with the inner aperture 30,forming a clamp groove 80 between the body ring portion 20 and the topshelf surface 70. The body ring portion 20 and the transition elbow aremade of stainless steel and the male tailpipe adapter 40 is made ofgalvanized steel, both of which are well-known to those schooled in theart. Both the body ring portion 20 and the male tailpipe adapter 40 andtheir respective component parts can also be made of other materials aswell.

There is a plurality of magnets 100 disposed on the top shelf surface 70for attachment to the tailpipe adapter used in combination with thevehicle exhaust removal system (not shown). The plurality of magnets 100are rare earth element magnets that are made from rare earth elements oralloys such as neodymium, samarium-cobalt or neodymium-iron-boron. Therare earth element magnets are usually plated to prevent breaking andchipping and are available in sintered and bonded forms. Rare earthelement magnets are also well-known to those schooled in the art and areused in a wide variety of magnet applications and are permanentlystronger than traditional iron magnets. The plurality of magnets 100permit the tailpipe exhaust nozzle device 10 to adhere to the tailpipeadapter (TA), in addition to the male/female attachment with theadjustable clamp groove 80 of the transition elbow, which allows thedepth of the nozzle when attached to the vehicle tailpipe to be varied.

The exhaust pipe nozzle device 10 also has a polymeric boot 90 attachedto the bottom 60 that is attached to an exhaust hose via the transitionelbow (TE) of the vehicle exhaust removal system, as indicated earlierin this figure description. The polymeric boot 90 is made of an ethylenepropylene diene monomer (EPDM) elastomer, which is a material that iswell-known to those well-known in the art and has many broadapplications. The polymeric boot 90 is also not limited to being made ofan ethylene propylene diene monomer (EPDM) elastomer and can also bemade of other materials as well. The exhaust pipe nozzle device 10, thebody ring portion 20, the bottom 60, the male tailpipe adaptor 40, theside 50 and the top shelf surface 70 and the transition elbow may or maynot be in the shape of a cylinder or other shape.

FIGS. 2A and 2B illustrate a second exhaust pipe nozzle device 200 usedin combination with a vehicle exhaust removal system to expel vehicleexhaust fumes from a building from a vehicle with a vertical stackexhaust pipe (not shown). The second exhaust pipe nozzle device 200 iscomprised of a body ring portion that may be in the shape of a cylinder210 with a bottom that may be in the shape of a cylinder 220 and aninner aperture 230, a male adaptor that may be in the shape of acylinder 240 with a side that may be in the shape of a cylinder 250 anda top shelf surface that may be in the shape of a cylinder 260 that isintegral with the inner aperture 230, forming a clamp groove 270 betweenthe body ring portion 210 and the top shelf surface 260. The body ringportion 210 and the male adapter 240 and their respective componentparts are both made of stainless steel, which is well-known to thoseschooled in the art. Both the body ring portion 210 and the male adapter240 and their respective component parts can also be made of othermaterials as well.

The second exhaust pipe nozzle device 200 also utilizes a plurality oftabs 280, each with an individual aperture 290, sidewardly protrudingfrom the bottom 220, to accommodate a means for attaching the secondexhaust pipe nozzle device 200 to the vehicle with a vertical stackexhaust pipe (not shown). The means for attaching the second exhaustpipe nozzle device 200 to the vehicle with a vertical stack exhaust pipeis a plurality of fasteners (not shown), either screws or bolts, both ofwhich are well-known to those schooled in the art. The second exhaustpipe nozzle device 200, the body ring portion 210, the bottom 220, themale adaptor 240, the side 250 and the top shelf surface 260 may or maynot be in the shape of a cylinder or other shape. The second exhaustpipe nozzle device 200 attaches to the vertical exhaust pipe of thevehicle and then connects to a flexible hose connected to the vehicleexhaust removal system, which then expels the hazardous fumes from thevehicle outside of the building that the vehicle is in.

The purpose of both the exhaust pipe nozzle device 10 and the secondexhaust pipe nozzle device 200 is to provide an attachment and automaticrelease from the exhaust tailpipe of a vehicle for the purposes ofremoving exhaust fumes from a building, while the vehicle is eitherstationary and running or moving. The exhaust pipe nozzle device 10 andthe second exhaust pipe nozzle device 200 are different than otherdevices that utilize rare earth magnets, pneumatic bladders orelectromagnets. The exhaust pipe nozzle device 10 and the second exhaustpipe nozzle device 200 can be used to remove hazardous exhaust fumesfrom fire stations, EMS stations, vehicle repair garages and otherbuildings where vehicles are emitting hazardous exhaust fumes.
